摘要:
The invention relates to an automatic system for monitoring the mixing of conglomerates. The inventive system can be used to monitor and measure the volume of a conglomerate, i.e. a concrete, mortar or other similar product, and the conditions in which the conglomerate is being mixed inside a mixer. The invention is characterised in that the system is provided with a sensor which rotates integrally with the mixer and which is fitted with a blade that is sensitive to the stresses exerted by the conglomerate thereon. The invention is also characterised in that the aforementioned information is transmitted to one or more terminals, by means of radio communication or other similar wireless communication means, for use in industrial processes.

The invention relates to a process for the granulation of sludge- and optionally dust-form material, in which the material to be granulated is mixed with hydratable or hydraulically settable solids and water, which solids react exothermically with water and act as binder in the mixture, where the solids are allowed to hydrate or set fully or partly, and where the mixture containing the fully or partly hydrated or set solids is shaped into granules, where the solids and, if desired, dust-form materials to be granulated are wetted or moistened with water, and subsequently and/or at essentially the same time the solids are mixed with the material to be granulated. The invention also relates to an apparatus for carrying out the process.
摘要:
The invention is directed to computer assisted manufacturing of industrial compositions, such as concrete. Aspects of the invention utilize wireless communications between a central processor and at least one field device having integrated circuitry. A process for initiating the automated preparation of concrete upon obtaining the weight of the solid ingredients is also disclosed.

A method comprising adding a suspension of a hydrophobic substance to a gypsum slurry. The hydrophobic substance may impart water repellent characteristics to the gypsum, may be used as a foaming aid, density reducer, dimension stabilizer, and others, and may increase the mechanical strength and durability of the gypsum product. In another embodiment of the present invention, suspensions of other substances may be used in addition to or in place of the hydrophobic substance to impart these characteristics.

The present invention relates to a network type automated concrete plant for efficiently producing and delivering ready-mixed concrete, and more particularly, to a network type automated concrete plant which can be collectively managed within a group of multiple ready-mixed concrete plants which are distributed and disposed in multiple regions which serve multiple construction sites and are equipped with a ready-mixed concrete producing apparatus, which is capable of realizing efficient operation, management and deployment. In this network type automated concrete plant, multiple ready-mixed concrete plants (20a), (20b) and (20c) are connected to each other through a plant center (10) by way of a network (14). A ready-mixed concrete truck (18) is deployed in each of the ready-mixed concrete plants (20a), (20b) and (20c), however the ready-mixed concrete truck is not fixed to any specific ready-mixed concrete plant, and is operated between a construction site and the closest ready-mixed concrete plant (20a), (20b) and (20c), and is then operated between another construction site and another ready-mixed concrete plant (20a), (20b) and (20c), in accordance with the operational status and requirements. A concrete mixer truck is used as the ready-mixed concrete truck.

A method for delivering concrete to a construction site comprises charging concrete ingredients into a concrete delivery mixing truck, mixing the ingredients, to form concrete of a slump, monitoring the slump of the concrete, adding water to the concrete to adjust the slump, storing the slump in a memory device on the concrete delivery mixing truck at least a plurality of times during delivery of the concrete, displaying the slump on a display device on the concrete delivery mixing truck, substantially repeating the method, unloading the concrete at the construction site, and downloading contents of the memory device to a computer located at a dispatch site for the concrete delivery mixing truck via a wireline transfer.

Methods and systems for forming hinged starch-bound matrices. Starch-based compositions are molded between heated molds in order to form a cellular matrix and also to remove the water from the starch-based compositions in order to form a binding matrix of solidified starch. The molding apparatus is configured to form one or more creases within the hinge area in order to define one or more lines upon which the hinge will bend. The molding apparatus is also configured such that the region of the mold corresponding to the inner surface of the hinge area will transfer heat more slowly to the inner hinge surface, resulting in reduced thickness of the skin of the inner hinge. This increases the collapsibility, or ability of the inner surface of the hinge to fold or buckle, during the bending action. This in turn reduces the bending radius of hinge such that the hinging action exerts less strain on the outer surface of the hinge. The inner surface of the hinge may optionally be treated with glycerin or other polyols soften the inner surface. The outer surface of the hinge may optionally be coated with an elastomeric material, such as polyvinyl alcohol, in order to strengthen the outer surface and reduce its tendency to fracture during the hinging action.

Methods and systems for readily and economically manufacturing hydraulically settable articles, particularly containers, from microstructurally engineered hydraulically settable mixtures. The mixture is pressed between a male die of a desired shape and a female die having a substantially complimentary configuration of the male die shape to immediately fashion a portion of the mixture into a form stable shape for the desired article. To assist in imparting form stability, the dies can be heated or cooled. Once the article has obtained form stability, the article is removed from the dies and dried under heated air to gain strength. The article can then receive printing or a coating, if desired, prior to packaging, shipping, and use.
摘要:
Compositions and methods for manufacturing sheets having a hydraulically settable matrix are disclosed. Suitable compositions are prepared by mixing together a hydraulic binder, water, and appropriate additives (such as aggregates, fibers, and rheology-modifying agents) which impart predetermined properties so that a sheet formed therefrom has the desired performance criteria. The compositions are formed into sheets by first extruding them into a sheet and then calendering the sheet using a set of rollers. The calendered sheets are dried in an accelerated manner to form a substantially hardened sheet. The drying is performed by heated rollers and/or a drying chamber. The hydraulically settable sheets so formed may have properties substantially similar to sheets made from presently used materials like paper, cardboard, polystyrene, or plastic. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have especial utility in the mass production of containers, particularly food and beverage containers.
